The beautiful, quiet and tailor-made solution
The AirSlide – an innovative and electric sliding roof window is unique on the market. As each window is made to measure in our production facility, the window is available in sizes from a minimum of 65 x 80 cm to a maximum of 110 x 150 cm and in the desired system color for your patio roof and co. The barely perceptible volume also creates an unclouded feel-good atmosphere. According to the physical principle, natural convection creates a vertically directed air flow, the so-called chimney effect. (See “What is a chimney effect?” below).
our products & The advantages
2020 was the year, ExtremeLine is German Design Award Winner 2022 for the AirSlide, the electric sliding roof window for patio roofs! We are overwhelmed and very proud!
For our AirSlide, the electric sliding roof window for patio roofs, we have received the German Design Award 2022 >> SPECIAL MENTION<< in the category of Excellent Product Design in the Gardening and Ourdoor Living sector. Particular attention was paid to the outstanding and innovative design in conjunction with the product benefits. Right from the start of development, it was clear that the AirSlide should convince with a clear and puristic design. Thus, much emphasis was placed on the material during the design. The choice fell on aluminum and stainless steel. With the AirSlide, we have also responded to our customers’ desire for closeness to nature and ensured the greatest possible incidence of light through the absence of interfering edges. A lot of daylight comes into the cold conservatory and an unobstructed view of nature is available. And what about the fresh air! The window elements slide over each other like a convertible and a lot of fresh air flows in. The hidden drive motor in particular completes our high standards for this innovation. The built-in tubular motor allows the window to open very quickly and almost silently, completing the clean look. Since 2024, we have optimally developed a solar drive that makes wiring the window superfluous and saves energy costs.

What is a kamine effect?
The actual chimney effect is based on heat flow: warm air in a conservatory rises and is drawn out through an open window, for example. This creates a negative pressure, which is compensated by an inflow of air. This fresh air contains more oxygen, which makes the room temperature and stay in it much more comfortable, despite the sun. Moreover, this process takes place on all heated surfaces such as radiators, cooling fins, house facades, etc., if the geometric shape and dimensional relationships resemble a chimney.
The special thing about this product is that it was developed and designed by a very small team and is therefore 100% Made by ExtremeLine. But that was not all! The AirSlide also offers the following advantages:






STATE-OF-THE-ART DESIGN
Modern and elegant overall appearance thanks to the reduction of the frame profiles to a minimum, the absence of interfering edges and a considerable proportion of glass. Innovative character thanks to concealed drive motor (tubular motor, 230 V). It enables the window to be opened very quickly and almost silently, thus completing the clean look. It also has purist lines.
The solar module also has a simple and clear design and fits perfectly into the overall appearance of the window.
HIGH QUALITY
Aluminum is the ideal material to integrate into the different design styles of a conservatory. This was one of the reasons why aluminum was chosen as the material for our AirSlide sliding patio roof. Because aluminum impresses with its unique elegance and material properties. We also attached great importance to quality and durability in the technical implementation and selection of all materials. We use tested materials from Otto Chemie for the adhesive bond and seal. Otto Chemie is one of the market leaders in highly technical and durable adhesive bonds and seals.
VERY PLEASANT CLIMATE
A key feature of the AirSlide electric sliding roof window is the very large opening area, as the roof window works according to the convertible principle. The glass elements of the roof window slide vertically over each other so that the window opens wide. This special sliding technology allows the window to be opened up to 70%, depending on the frame size. This is far more than is possible with comparable windows. This allows plenty of fresh air to enter and sustainably improves the indoor climate in your greenhouse.
SIMPLE INSTALLATION
Large inspection opening for cleaning and maintenance work on the roof or the building elements above. Thanks to its system-independent installation, the AirSlide roof window is suitable for use in almost any patio roof and cold conservatory according to the plug-and-play principle. It is installed like a pane of glass with clamping strips, making it easy to retrofit the window in an existing patio roof. The result is more temperature control, air and living comfort. A heat protection awning can also be fitted for the summer.
MADE IN GERMANY
In addition, our AirSlide is the result of innovative research and technology and is one hundred percent “Made in Germany”. The window was tested and certified in collaboration with a recognized Rosenheim institute. Corresponding test certificates attest to first-class values in terms of driving rain tightness, air permeability, wind load and sound insulation. It is also lovingly handcrafted here at the company headquarters in Halfing and tested before dispatch.
Control system
You can easily open and close your sliding roof window and sunshade at the touch of a button. Furthermore, with Somfy IO, it can also be controlled and configured via Android smartphone as well as voice assistants. In addition to Somfy IO (HomeControl IO), Warema WMS is also available as a radio system. You want more information about controls? You can find them here:

Ecodesign guideline
The AirSlide is a product covered by the EU Construction Products Regulation. Thus, in accordance with the declaration of performance, air permeability, driving rain tightness and resistance to wind were tested at the PfB Prüfinsitut für Bauphysik in Rosenheim. Of course, the structural analysis is also available for the structural engineer.
FACTORY CONTROL
From the factory, the AirSlide can be controlled with any mutually interlocked up/down pushbutton. In addition, the leading control systems such as Somfy IO or Wareme WMS can be supplied as standard. We will be happy to advise you on this as well.
Old equipment take-back
The AirSlide is of course registered for the return of old appliances or will be taken back.
